need phone support

Question

BASE株式会社の野田と申します。

御社のサービス（BitLocker）の仕様について電話でのサポートを希望します。

Answer 1

Only English support is available.

For phone support about BitLocker specifications, use Microsoft’s official customer service phone numbers page and select the appropriate country/region, then follow the prompts to reach technical support:

1. Open the global phone numbers list: Customer service phone numbers - Microsoft Support.
2. Choose the country/region.
3. Call the listed number.
4. When prompted, indicate that the issue concerns a business account and BitLocker/Windows security.

For Microsoft 365 for business administrators, technical support is available 24x7 by phone. Have admin account details ready when calling. A PIN-based verification step may be required; the support agent sends a verification code to the registered email or phone number in the Microsoft 365 admin center profile.

If the account is personal (non-business), use the same phone-numbers page and, if no phone option is shown, select the “Get Help” option on the support site to reach support via web.
